    2013年-2015年广州市水源水中耐热大肠菌群分析

    Analysis on Thermotoletant Coliform Bacteria in Source Water of Guangzhou during 2013-2015

    • 摘要:
      目的 对2013年-2015年广州市市政水厂和自建水厂水源水中的耐热大肠菌群指标进行分析,了解广州市水源水的微生物污染状况。
      方法 使用Excel软件对2013年-2015年广州市市政水厂和自建水厂水源水中的耐热大肠菌群数据进行整理,使用SPSS 18.0软件对数据进行分析。
      结果 2013年-2015年XJ、BJ、DJ和LXH四个水域的耐热大肠菌群平均检出值分别为1.2×104、1.7×104、3.55×104和1.4×105个/L,均超出《地表水环境质量标准》(GB 3838-2002)的Ⅲ类1.0×104个/L水质标准的要求,合格率分别为37.5%、16.7%、25%和0。LXH耐热大肠菌群值高于XJ和BJ,合格率明低于XJ。XJ第三季度耐热大肠菌群值高于其余季度,合格率低于第一季度和第四季度。
      结论 LXH与其余江水相比较,受粪便污染的程度相对较重。XJ第三季度的耐热大肠菌群检出最高,应重点加强水源防护,并依需调整水消毒工艺。

       

      Abstract:
      Objective To analyze the thermotolerant coliform bacteria index in the source water of municipal and self-built waterworks during 2013-2015 in Guangzhou, and to know the microbial contamination in source water.
      Method The data obtained from GZ municipal and self-built waterworks were analyzed by SPSS 18.0 statistically.
      Results The average thermotolerant coliform bacteria counts detected from the source water in XJ, BJ, DJ and LXH districts were 1.2×104, 1.7×104, 3.55×104 and 1.4×105/L, respectively, which were all exceeding 1.0×104/L, the standard limit for the grade III of water qualify in the Surface Water Environmental Quality (GB 3838-2002), and the qualified rates were 37.5%, 16.7%, 25% and 0 respectively. The detection rate of thermotolerant coliform bacteria in LXH was higher than that in XJ and BJ districts, and the qualified rate in LXH district was obviously lower than that in XJ district. The detection rate of thermotolerant coliform bacteria in XJ in the third quarter was higher than other quarters of a year. The qualified rate was higher in the first and the fourth quarter of a year.
      Conclusions Comparing to other districts, the contamination of thermotolerant coliform bacteria in source water in LHX district was more serious. The detection rate of thermotolerant coliform bacteria in XJ district in the third quarter was higher than that in other quarters of a year. Therefore, we should focus on strengthening water protection and adjusting water disinfection process in accordance with the needs.
